Data processing method and device, equipment and medium

The invention relates to a data processing method and device, equipment and a medium. According to the method and the device, the first control chart is displayed to display the plurality of data nodes in the first control chart, so that a user can replace any data node displayed in the first control chart, and the data entry interface can be displayed in response to the node replacement operation in the first control chart; the second control chart is generated based on the data set corresponding to the data node except the replaced data node in the plurality of data nodes and the simulation data set by acquiring the simulation data set through the data entry interface, and a new simulation data set can be acquired without reproducing a product, so that a large amount of time is saved, and the production efficiency is improved. Therefore, the product quality analysis efficiency in the production process can be improved, and the product quality monitoring capability in the production process is improved.
